The Icom IC-756 covers all nine HF ham bands plus 6 meters (receive from 30 kHz - 60 MHz). The high resolution 4.9 inch monochromatic TFT dot matrix LCD display provides more operating information than you've ever had before, including a spectrum scope function. The Icom 756 is shown above with the optional PS-85 power supply and optional SP-21 external speaker. The 756 requires 13.8 VDC at 20 Amps. 13.375 x 4.375 x 11.25 inches 23.1 lbs.
